To all whom it may concern:

Be .it known that I, PETER J. Pn'rnnson, citizen of the United States,-residing'at Oakland, in the county of Alameda and State of California, have mvented. new and useful Improvements in Liquid-Measuring Devices, of which the following is a specification.

My invention relates. to a device which is especially designed for accurately and simultaneously measuring liquids and transferring liquids from a receptacle or holder-to a receiver.

It consists in the combination and arrangement of arts, and details of construction, which w1l be more fully explained by reference to the accompanying drawings,in

' which Figure 1 is a art elevation and part sectional view of a quid measuring device embodying my invention. Fig. 2 is a transverse section through line XX of Fig. 1.

It is the object of my invention to provide 1 convenient and accurate measuring device and draw-off attachment for bottles or other receptacles, so that the amounts drawn v therefrom can be accurately known.

As shown in the drawings, A re resents a bottle or receptacle of any suitab echaracter, say of glass or other transparent material having an extension formed upon. one side and near the bottom, as shown at 2. This extension has a vertically formed, slightly tapering chamber closedat the bottom, and the top open and adapted to receive a plug 3, the interior of which plug has a graduated chamber 4; and the to of the plug may be rovided with any suita le handle or thum -piece 5 by which it can be per portion of which connects through a.

turned. Through the extension 2 are made two assages, the upper passage 6 connect-. ing t e lower part of the receptacle A with the upper part of the chamber 4 of the, plug, and t e lower assage 7 soformedas to com nect with the ower art of the chamber 4. 45

As before stated e plug ishollow to pro- Nide an interior gra uated chamber, the uppassage 4 with the upper passage'6 in the extension 2; Through one side of the lower ortion of the lug and connecting with the ower part of t e graduated chamber, is another passage 4 which connects with the lower assage 7 in the extension 2 whereby I when t e plug is turned in one direction the said passages 6. and 7 in the extension.

passages 4 and 4 register with the afore- Specification of Letters Patent. A ncaaonmea ma o, 1908. Serial No. 442,551.

I Upon the exterior portion of the chamber 2' are made the dischar e passage .8 at the lower part, and an air i et passage 9 at the u per art.- These passages coincide with tlib hoi zontal' plane of the passages 6 and 7 rE'rER'J; PETERSON, OF" OAKLAND, CALIFORNIA.

where they open into the vertical chamber In which the'plug 3 is turnable; and when the plug'is turned so that the openings in its 'side coincide with the passages 6 and 7, liquid will flow from the receptacle A into the graduated chamber 4 to any desired ex The tendency of the liquid will be to pass in through the lower passa e 7;, and air which may be within the cham er 4 will be forced out through the upper passage 6. I have. found it preferable, however, to make a sup lementa pipe or passage in the form of a y-pass 10, the upper end of whichv opens into the upper part of the receptacle A, and the lower end communicates directly with the assage 6 so that as the liquid flows through t e passage 7 into the lower part of' the chamber 4, the air in the chamber will be forced out through the passage 6 andthe b pass 10 into the upper part of the bott e, without pass' through the liquid in the bottle, as wil l he the case if the by-pass is not present. V

When the desired quantity of liquid has been received into the chamber 4,-the plu 3 is turned so that it stands at right ang es with its former position, and the openings in the plvug are cut off from the passages 6 and 7. 90

henit is desired-to Withdraw theliquid from the chamber in the plu the plugis turned another quarter revo ution, which brings the'openings in its side into register with the passa es 8 and 9. The liquid can then flow out through the passage 8, and air will be freely admitted through the passage 9 to take the place of the escaping liquid.

The whole device forms a convenient, permanent attachment for receptacles containing easily vaporized, corrosive or other liquids which it is desirable .to have measured and transferred with accuracy.

By havin a plurality of plugs with chambers of di erent sizes and with different graduations, the'single apparatus may be ada ted to many uses.

aving thus described my invention, what Iclaim and desire to secure by Letters Patent is'- v 1. The combination with a liquid receptacle, of an extension formed integral therewith, said extension having a vertlcal chammade of transparent material and said plug having graduations which are observable throu h the material of said extension.

2. %he combination with a liquid receptacle, of a transparent extension formed integral therewith, said extension having a vertical chamber, a hollow plug turnable in said chamber and having passagesleading through its side at the up er and lower portions, said the u er portion of t plug having gra nations which are ca able of eing seen through the material 0 said extension said extension having passages adapted to register with the passages in the plu and having other passagles into register Wit which the passages in t e plug may be turned for the dischar from the upper passage of said extension to e receptacle.

e combination with a bottle or receptacle, of an integral extension of transparent material having a vertical chamber closed at the bottom, a hollow graduated plug fitting and turnable in said chamber,

which the assagesgo of the liquid con-, tents, and air conducting means extending said plug having openings into the top and bottom of the gra uate space, said rece tacle havmg a assage leading from tl ie lower portion and registering with the lower opening of the plug, a ipe forming a by-pass 4. In an apparatus oflthe character described, a bottle or receptacle having a verticall chambered extension rigid therewith, sai extension being formed of transparent material and having passages connecting the upper and lower part of the-chamber with the interior of the receptacle, a hollow plug forming a graduated chamber and havin openings in the up er and lower part adapted to register with t e passages in the receptacle, said extension havim discharge and air inlet assages with which the plug may be turned to register.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- PETER J. PETERSON.
